1c, 1883,No.61,9fi5,audin e 7 To aZZ whom it may concern.-

Be it known that I, HENRY Dunsnnne' BossoN, a citizen of Belgium, residing at Verviers, Belgium, have invented certain new and 5 useful Improvements in Fleece-Dividing Attachments for Oarding-lliachines; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it 1 appertains to make and use the same.

My invention relates to attachments to carding-machines, by means of which the rollers carrying the dividing blades are vibrated. These dividingblades receive and divide the I web or fleece of wool as it comes from the condenser, and in the devices nowin use they are laterally stationary and work always on the same lines or places upon the dividing-aprons. The waste, dust, or tly from the cards gathers in the spaces between the blades, and unless cleaned off is liable to enter the rubbing parts and cause irregularities in the ends, and the blades working always in the same places on the aprons eventually wear into the leather aprons, forming ridges therein, thus making said aprons practically unfit to work with any other size or number of blades. Particularly is this the case where the dust or fly is allowed to accumulate between the blades and get un- 0 der them in considerable quantities at a time by accident.

The object of this invention is to obviate these difliculties and cause the dust or fly to be cleaned oit regularly and thoroughly, and to 3 5 gradually and regularly change the position of the blades upon the apron. This object is attained by giving to the rollers which hold the blades a slow forward-andbackward motion in the direction of their length, whereby the series of blades on both of said rollers are constantly changing their positions on the aprons. This constant change of position of the blades,

by sliding over the aprons, serves to clear or clean the dust and fly from the entire surface 5 of the aprons, and entirely overcomes the objections to the use of the stationary blades.

The following detailed description by figures and letters will more clearly and fully explain the nature and operation of my said invention.

The accompanying drawings illustrate what I consider the best means for carrying my in vention into practice.

In my said drawings. Figure 1 is an end ele* vation of the attachment, or that portion of it which illustrates the application of my in1-, v

provcn1ents,with the framing removed. Fig.

2 is a front view of the same, showing the means for reciprocating the blade-carrying rollers. Fig. 3 is a perspective view of the front of a machine having the features herein described and claimed in connection with other operative parts of the device.

Similar letters of reference indicate corresponding parts in all of the figures.

A Aare the bladecarrying rollers.

a a are the series of blades, fastened to their respective rollers in such a manner as to cause the blades on one roller to match or register with the spaces between the blades 011 the other roller. The said blades are of such pli- 7O able character as to interlock or interlie with cachother after leaving their respective roll ers.

B B are the dividing-aprons carried by roll ers b I), respectively. 5

The blades a a are bent over the abutting endsor curves of their respective aprons and held upon them by confining-rollers c 0, as

shown.

The construction thus far indicated by ret'- s erence-letters is substantially that which is already known, and the operation of the bladecarrying rollers to produce the reciprocation of the blades in their longitudinal direction is v attained by means ordinarily employed for this purpose, and may consist of the cranks 0 0, connected together by link 0', and 0pcrated by the pitmanrod p, which is connected to crank-wheel g, which latter is driven by a .train of gearing from the powershatt r. The

disk G also receives motion from the same source by'means of the gear and worm s, ratchet t, and pawl a, secured upon the pin of one of the cranks 0.

My invention, as already stated, consists in 5 vibrating or reciprocating the blade-carrying rollers with a slow and even forward-and-backward movementin the direction oftheirlength,

whereby the blades and moved over the entire exposed surface of the aprons, and do not rest thereon at any one point for a moment. The amount of movement necessary to cover the entire width of the aprons by the reciprocations of the blades will, as can be readily seen, not much if any exceed the width of a single blade, and the movement, while constant, must be or. preferably is slow and regular. The blades being held securely upon the aprons and in close contact therewith by the confining-rollers c c, the back-and-forward movement of the blade-carrying rollers will cause the said apronsto be cleaned of all dust and fly, and at the same time the aprons will not be worn in groovs,as would be the case if the blades always followed the same track. The wear being evenly distributed over the entire surface of the aprons, the width or number of the blades may be changed at any time, and they will work upon the old apron with the same facility and effect as upon the new one.

The reciprocation or vibration of the bladecarrying rollers may be effected in any desired manner. The entire frame in which they are mounted. may be moved, I have shown the rollers with elongated gudgeons or journals, as shown at a", working in boxes d d, which perinitthem to be moved longitudinally. A yoke, E, secured upon the gudgeons in such a manner as to permit their rotation, but to control their longitudinal movements, unites the two rollers. A lever, F, with a slot, f, for resting over crank-pin g on wheel G and fulcrumed at f, is pivoted to a connecting-rod, F, which is pivoted to the yoke E. By'the rotation of the wheel G the lever F and link F are caused to reciprocate the yoke E, which causes the reward movement of the blades over the aprons; 0'

but this mechanism for producing this result may be varied and any other construction capable of effecting the same result substituted in its place. I

The character of machine to which the herein- 4 5 described attach ment is applicable may be seen in patent to J. S. Bolitte, No. 312,424, February 17, 1885, which shows the means for producing all the actions of the rollers andblades, except the longitudinal movement of the rollers A A, which is provided for in this application.

Having thus described my invention,whatl claim, and desire to secure by Letters Patent,

1. The combination of the dividing-aprons, dividing-blades, longitudinal rollers on wh ch the blades are secured, and means for reciprocating said rollers, substantially as set forth.

2. The combination of the dividing-aprons, dividing-blades, and rollers for carrying the. same,with means, substantially as dQSQIlbQd, forreciprocating or vibrating the blades upon the aprons, as set forth.

3. The combination, wit-h the dividingaprons, dividingblades, and rollers on which said blades are secured, of the yoke E, the lever F, and connectingrod F, and wheel G, having crank-pin, all substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
